Consuming large amount of heap memory

Our project is consuming over 2GB of memory, running out of memory in CI without bumping the default node limit, like this: NODE_OPTIONS: "--max-old-space-size=6144".

--verbose shows: Heap stats: total_memory_size=36864MB, total_free_size=73MB, total_heap_size=2427MB, used_heap_size=2315MB, cross_worker_used_heap_size=2315MB, total_physical_size=2424MB, total_available_size=1776MB, heap_size_limit=4144MB

Full output: https://gist.github.com/xixixao/3a4355735b5f4218a6f07d68ab8c8b2c (it's 100K+ lines - is that expected / desirable? - it's from an older version, but latest 1.1.404 gives the same stats)

Start by reproducing pyright -p /foo/pyproject.toml --stats against the reported 918 source files and capture the heap statistics shown by --verbose. Review the linked full output and compare the current results with pyright 1.1.402 and 1.1.404; the issue is complete when the memory behavior is explained and an actionable fix or confirmed expected behavior is documented.
